Title: Apparatus and method for marking elongated articles
Inventor: LABBE JACQUES
IPC: G05B19/12
Filed: 1998-08-20
Granted: 2001-06-26
Abstract: An apparatus for marking elongated articles such as lumbers while being longitudinally conveyed, and for providing a reliable reading of the applied marks to obtain associated coded information related to the article. The apparatus comprises a marking station followed by a remote reading station. The elongated article is transported on a longitudinal conveyor through the marking station which receives coded information related to the article to be marked, such as identification and/or grade/dimension data. The reading station comprises upper and lower pairs of luminescent ink-jet devices for applying a corresponding information mark pattern on either or both top and under surfaces of the elongated article, which information mark pattern longitudinally extends on each of the marked surfaces.      After being handled, the marked article is transferred to a transversely moving conveyor, which transports the marked article through the reading station which is provided with a plurality of optical sensing devices each having luminescence inducing light source, to produce an output signal corresponding to the coded information. A method for marking and reading coded information onto an elongated article ensures reliable article identification whenever the article was turned upside-down while being handled between marking and reading steps.

Abstract: Externally mounted enclosures for mobile radio base stations potentially experience a wide range of ambient temperatures.  In temperate climates, it is possible for the heat generated by the internal electronics to be dissipated. by natural convention.  In hotter climates this becomes difficult or impossible, however.       An enclosure is disclosed having an inner case 2 for containing the equipment.  The case 2 is formed with heat conductive fins 4 extending vertically, in use, so as to define channels 8 therebetween.  An outer case 10 contains the inner case and defines air passages 12 into which the fins project.  The outer case has vents 14 and 16 to allow convection through the channels between the fins.  A fan unit 24 is located at or towards the upper end of the air passages and laterally of the air passages to draw air therefrom.   Control means is provided for controlling operation of the fan unit according to temperature.       The fan unit is located so that it does not obstruct the air passages and thus does not impede natural convection.  When the fan unit is switched on, it increases the flow of air in the channels between the fins so increasing cooling.

Abstract: A system for accessing resources, such as bitmaps, fonts and sound files is provided. Typically, resources of this type are accessed as files from Java code. The data is read into dynamic (RAM) memory as a byte array in a Java object, and at least one other copy of the byte array is made in order to process the resource data, such as rendering an image to a display. The invention provides a mechanism for accessing the resource data directly from ROM, without making intermediate copies in RAM. Each resource can have a unique key or string in a logical table.  Values associated with the keys are pointers to the data stored in ROM. The pointers are passed directly to the methods for processing the data on the hardware, bypassing the need to have the data become a temporary Java object. The saving in memory use is particularly advantageous for constrained memory devices. Applications developed for environments using traditional file access can be ported to a ROM-access environment by including a global switch redirecting resource calls to the logical table(s) containing the keys.
